What's faster: Regex or string operations? [closed]

Answer 1

I did some profiling in C# a while back, comparing the following:

1)LINQ to Objects.

2)Lambda Expressions.

3)Traditional iterative method.

All 3 methods were tested both with and without Regular Expressions. The conclusion in my test case was clear that Regular Expressions are quite a bit slower than non-Regex in all 3 cases when searching for strings in a large amount of text.
